System of linear equations

Abstract

This work is carried out within the framework of the "Educational Practice IV" residency of the teacher training course for Mathematics teachers; the objective is to carry out an investigation on how to accurately define systems of linear equations for their better implementation in the classroom, achieving a graphic and algebraic approach, observing their implications, solutions and applications. The information obtained from this research is a valuable resource for the planning of the didactic proposal developed in the 4th year of the Edgar Osvaldo Juan Morisoli Secondary School of our city -Santa Rosa, La Pampa -, with students of the morning shift. We work on the relationship between mathematical foundations and those of Didactics of Mathematics, curricular materials, editorial sources and the classroom proposal implemented. Thus, while the mathematical arguments mark positions of the discipline, the review of works and research related to teaching and learning, the objective is to identify concerns, problems and needs; from the editorial sources, logics, exercises and classroom problems are described, and the curricular materials indicate concepts and theories by way of prescriptions and ministerial recommendations of our province. This framework helps to explain and describe decisions made and moments in the implementation of the proposal.
